St George Wharf Tower is a 180m tall residential building alongside the River Thames in south west London. The tower sprang to fame in January 2013 when the construction crane was hit by a helicopter in January 2013.

This 50 storey tower opposite Lloyd’s of London rises to a height of 224.5 metres (802 feet). It has been given the name "The Cheese Grater" due to its wedge shape that makes it look like a kitchen utensil of the same name.
